be quiet! Light Wings PWM High Speed Addressable RGB Fan 140mm

LIGHT WINGS - 140mm PWM High SpeedIMPRESSIVE LIGHTING, SUPERIOR COOLINGLight Wings 140mm PWM high-speed offers impressive illumination for a vibrant unique look, strong performance and quiet operation with efficient cooling.- ARGB lighting on front and rear- Multiple colors and modes for an individual look thanks to 20 LEDs- 9 silence-optimized fan blades for high pressure and low noise-generating turbulences- Remarkable performance-to-noise ratio with 31dB(A) at 2,200rpm- Long life rifle-bearing gives an operating lifetime of 60,000 hours- 3-year manufacturers warrantyIf you are looking for a high-speed fan with an impressive look from every angle, Light Wings 140mm PWM high-speed is your fan of choice.IMPRESSIVE LIGHTINGLots of illumination possibilitiesLight Wings 140mm PWM high-speed offers ARGB lighting at the front and rear. The subtly lit ring at the back combined with the bright one at the front make for a magnificent appearance from every angle. 20 ARGB LEDs give you many opportunities to individualize your PC build.FOR RADIATORS AND HEATSINKSFan blades optimized for high pressureWith a remarkably high air pressure of up to 2.3mm/H2O, Light Wings 140mm PWM high-speed is the best choice for water-cooled and air-cooled systems alike. The 9 airflow-optimized fan blades provide enough air pressure to make this fan perfect, even in demanding configurations.QUIET OPERATIONAcclaimed be quiet! low noise levelA highly optimized impeller achieves the silent operation be quiet! is famous for. With a noise level of 31dB(A) at maximum fan speed, it proves that instead of being a replacement the lighting is an addon to silent and very powerful operation. All features combine to make Light Wings 140mm PWM high-speed the fan of choice for silent show cases and gaming systems alike.VARIABLE FAN SPEED FUNCTIONAdjusts the fan speed and associated noise levelPulse Width Modulation (PWM) allows compatible 4-pin controllers, including those built into many motherboards, to intelligently vary the speed and thus the noise level of the fan. With PWM the system can ramp up the cooling when its needed, or operate in maximum quiet mode when its not.General DataModel: Light Wings 140mm PWM high-speedDimensions (mm): 140Color option: BlackLighting: ARGB LEDFan speed @ 100% PWM / 12V (rpm): 2200Noise level @ 100% PWM / 12V (dB(A)): 31Air Flow @ 100% PWM / 12V (CFM / m3/h): 71.7 / 121.82Air Pressure @ 100% PWM / 12V (mm H2O): 2.3Mechanical SpecificationsDimensions (L x W x H), (mm): 140 x 140 x 25Weight incl. fixed cables (g): 251Bearing technology: RifleMotor technology: 4-pole fan motorPush pin fixing: -Screw fixing: YesCables / ConnectorsDaisy chain for lighting signal: YesLighting connector: 5V 3-pin ARGBConnector: 4-pin PWMCable length (mm): 500Cable sleeve: -Performance / NoiseAir Flow @ 100% PWM / 12V (CFM / m3/h): 71.7 / 121.82Air Pressure @ 100% PWM / 12V (mm H2O): 2.3Noise level @ 100% PWM / 12V (dB(A)): 31Lifespan (h / 25C): 60,000Electrical SpecificationsRated Voltage DC (V): 12Operating Voltage DC (V): 5 - 13.2Current consumption (A): 0.16Safety current (A): 0.39Input power (W): 4.68Rated Current LED (A): 0.67Accessories3-pin to 4-pin 12V-connector: -12V to 7V adapter: -12V to 5V adapter: -Screws: 4Push pins: -hard plastic washer: -Others: -Safety CertificationApprovals: CE / RoHs / RU / WEEEEnvironmental DirectivesRoHs: -Triman: -Logistics DataArticle number: BL075Dimensions, package (L x W x H), (mm): 173 x 153 x 29.5Gross weight, package (kg): 0.334-Product Type: FanFan Size: 140mmMax Fan Speed: 2200RPMFan Colour: BlackLED Colour: Addressable RGBConnections: 4-Pin PWM & 3-Pin ARGB
